What You Did
You found a way to capture an ice cube with a piece of yarn.
Intended Results
The yarn should not have stuck to the ice by itself, but it should have stuck to the salty ice
Unintended Results
If you didn’t use enough salt, or if you didn’t wait long enough to pull on the yarn, it may not have stuck to the ice very well.
Keep Tinkering
Try using sugar instead of salt
